Definitions

  • This disclosure relates to a method for the manufacture of reactive intermediates for the manufacture of polyetherimides.
  • One method for the manufacture of polyetherimides is known as the "displacement polymerization" process.
  • Synthesis of polyetherimides via the displacement polymerization process includes imidization as described, for example, in U.S. Patent No. 6,235,866, to produce a reactive bisphthalimide intermediate substituted with a leaving group; synthesis of a salt of a dihydroxy aromatic compound, as described, for example, in U.S. Patent No. 4,520,204; and polymerization by reacting the substituted bisphthalimide and the salt, as described, for example, in U.S. Patent No. 6,265,521.
  • imidization generally proceeds by reaction of 2 moles of a phthalic anhydride substituted with a leaving group with 1 mole of diamine in a reaction solvent, such as o- dichlorobenzene (oDCB).
  • a reaction solvent such as o- dichlorobenzene (oDCB).
  • the reactive bisphthalimide intermediate is obtained as a slurry in the reaction solvent, which can be used directly in polymerization.
  • the thixo tropic nature of the bisphthalimide slurry causes adhesion to reactor walls and other internal equipment, such as stir shafts, stir blades, and baffles. This can lead to high levels of the reactive bisphthalimide intermediate contaminating the final polyetherimide product. It can further lead to other processing problems, such as difficulty in achieving thorough mixing and difficulty in sampling the reaction product. Further, the rate of polymerization is dependent on the dissolution rate of the
